1. Develop a robust and rapid eddy current characterization method that can describe how eddy
currents perturb the scanner’s magnetic field. Test the ability of these characterizations to improve echo planar and spiral thermometry and diffusion MRI sequences. Publish models of the eddy currents of both a 650 kHz and 220 kHz transcranial transducers as a function of their position and azimuthal angle in an MRI scanner.
2. Develop maximized energy deblurring algorithms for MR thermometry. Acquire temperature precisions and accuracy estimates in phantoms. Acquire temperature precisions estimates in human volunteers. Compare the results to the previous spiral MR thermometry method and to the current clinical thermometry implementation.
